Joint Effort Initiative Discussion Group

Agenda - Friday 17 March 2023 Meeting at World Congress in Denver

The Joint Effort Initiative (JEI) Discussion Group is an international collaboration of 100+ researchers (22 countries, 6 continents), clinicians, consumers, and consumer organizations who are concerned with the implementation of evidence-based, cost-effective, osteoarthritis care for all, particularly through coordinated osteoarthritis management programs (OAMPs). Our mission is to investigate the best osteoarthritis management program models to use, develop long-term strategies for effective implementation of these programs in different socioeconomic and cultural environments, and identify research priorities to facilitate best evidence care internationally. Priorities for the work of the JEI were established in 2018 through an international survey and consensus study (https://www.oarsijournal.com/article/S1063-4584(19)31046-5/fulltext).

Our current projects fall under the themes of:

  • Implementation of OAMPs
  • Measuring Clinical Outcomes
  • Education and Training for Healthcare Professionals

JEI members are invited to participate in working groups or special projects undertaken by the Initiative.

Gait Biomechanics Discussion Group

The Gait Biomechanics Discussion Group was established in July 2023.  The objectives of the Discussion Group are to build more cross-institution, international collaborations, develop larger biomechanics datasets, identify and use best-available biomechanics methods, change approaches to biomechanics measurements to meet modern availability and requirements (e.g., out of laboratory, in-clinic) and encourage transfer of knowledge for improvement of patient outcomes.

In addition, the Discussion Group hopes to increase visibility of biomechanics throughout OARSI, improve acceptance rates for biomechanics-related oral presentations at OARSI World Congresses, raise awareness, acceptance, and implementation of biomechanics research in the study and treatment of OA and improve rigor of biomechanics methods in OA research.

Chairs: Laura Diamond and Michael Hunt

Imaging Discussion Group

Agenda - March 18, 2023 Meeting at World Congress in Denver

June 22 Webinar:  View the recording hereClick here for more details.

The OARSI Imaging Discussion Group was created to bring clinicians, radiologists, imaging researchers, and industry representatives together to discuss OA imaging and the latest trends. The group provides a forum to review State-of-the-Art imaging technologies and their application in clinical settings. In addition, members discuss clinical translation, education, and gaps in research. The group also provides an expert forum that may be used during the approval process of imaging biomarkers by regulatory agencies. The Imaging Discussion Group meets yearly, typically around the OARSI World Congress. The outcome of this meeting often results in the composition of review articles, white papers, and/or position statements.

International Foot and Ankle Osteoarthritis Consortium Discussion Group

Meeting - Sunday, March 19, 7:00-8:30 pm at World Congress in Denver AGENDA

The International Foot and Ankle OA Consortium Discussion Group was established in January 2019 and endorsed by OARSI as a Discussion Group in May 2019 at the OARSI World Congress in Toronto. The discussion group brings together a network of clinicians, scientists, and other health professionals/key stakeholders who share a common interest in foot and ankle OA. Its aim is to drive the research agenda related to OA setting research priorities in foot and ankle OA to maximize progress and impact that will ultimately improve outcomes for people with OA. A secondary aim is that the foot and ankle could also be viewed as an untapped ‘case study’ into OA research, that if given more focused and collaborative attention internationally may provide some additional insights into the aetiopathogenesis of OA in general.

International Hand Osteoarthritis Consortium Discussion Group

There will not be a Hand Discussion Group meeting at World Congress in Denver.

The Hand Osteoarthritis Consortium Discussion Group focuses on defining priorities for hand osteoarthritis research. The group brings together clinicians and healthcare workers, academics and scientists, and key stakeholders. At the OARSI 2021 Congress, the Discussion Group provided an online forum to discuss in particular whether different hand osteoarthritis phenotypes exist. An electronic polling system was used to assess consensus between the Discussion Group attendees, and the results were shared in real time. It is also planned that the results will be submitted for publication. Future meetings are anticipated to run annually at the OARSI Congresses, and these are likely to provide both networking and discussion opportunities for anyone interested in the hand osteoarthritis field.

Chairs: Kari Shah and Nigel Arden

Multimorbidity Discussion Group

The Multimorbidity Discussion Group was established in July 2023.  The objectives of the Discussion Group are to (i) to map research priorities in the field; (ii) to build multidisciplinary and international collaborations that could bring together the different expertise needed to investigate multimorbidity and its impact on ageing; (iii) map existing cohort and dataset for the study of multimorbidity; (iv) to advocate a shift in OA management from a single disease approach to a more holistic, patient-centric process that considers the interplay of multiple health conditions on ageing and overall well-being.

Chair:  Andrea Dell'Isola

Pain in Osteoarthritis Discussion Group

Meeting:  Friday, March 17, 2023, 12:00-1:30pm at World Congress in Denver
